Water Flow/Pressure Decreased Affer Installing Combi Boiler

Postby Steven5 » Thu Mar 21, 2019 12:04 am


My landlord has installed a combi boiler recently and I’ve noticed the water flow/pressure from the hot taps have decreased significantly.

Before the combi we had a gravity fed system with a 3.0 bar pump and the flow was 10/10 in all taps.

Also when I turn the hot water tap on full, it takes about 15-20 seconds before it starts getting warm/hot

Is there any pumps for combi boiler system that can help pressure increase ?and for the hot water to heat up quicker??
